PLEASANTON — Foothill High School was briefly locked down Tuesday afternoon after a short police pursuit led to a suspect running onto the school’s campus, according to the Pleasanton Unified School District.

The suspect, an adult male who was not a student, was arrested 10 minutes later, according to police. His name was not available Tuesday evening because he had yet to be booked, Sgt. Michael Dunn said.

The lockdown occurred at about 3:30 p.m., district spokeswoman Myla Grasso said.

Prior to that, Pleasanton police officers were attempting to pull over a vehicle on Foothill Road near the Laguna Oaks subdivision. Dunn said the officer attempted to pull the white, four-door car over for a mechanical violation, but the driver took off instead.

“They left the vehicle and ran onto the Foothill High campus,” Grasso said.

School administrators and a school resource officer followed the suspect and reported his location to officers.

“They ordered a lockdown,” Grasso said.

The students were moved away from the location of the suspect’s arrest, the “D” building, she said.
